Re: Seized Engine
Sorry to hear that, I would remove the engine then remove the cylinder and piston and wash out the crankcase with safety solvent or premixed fuel. I place a towel over a catch bucket and pour out the cleaning fluid through the towel catching the debris. In the future if you are removing the cylinder from a engine that you think has broke rings first raise the cylinder enough to get a shop rag under it and cover the openings into the crankcase, this will keep broken ring parts from falling in the engine. I learned that the hard way back in the motocross days. Did you replace the complete top end or just the piston? If the cylinder was scared by the first piston that could be why it locked up. Check the connecting rod to make sure it is not damaged or bent.
Your results may not be the same,Greg
